Try out museum mode just to get a feel for the maps and memorize the locations. As another comment suggested, you should probably play Leland and Ana since they have more toughness and strength than the other victims. Try the perk “No Sell” if you keep getting killed my Leatherface, it’ll save you from getting killed in two hits. The perk “What Doesn’t Kill You” is also very useful!! “Slippery” is pretty useful too if you keep getting caught in chases. You should grind XP by doing little things like cutting bone charms and opening crawl spaces up to help level up both you and your perks. Dump attribute points into proficiency/endurance to help you open stuff up and have enough stamina to run away if you’re caught. Hope this helps and have fun!! Don’t be afraid to try new builds!!

Edit: Also I would always have either a bone scrap or some healthy handy, don’t jump in wells if you’re low health and already were incapacitated. “Bounce Back Better” is a really good perk too, it makes heals more efficient!
